Autumn


Autumn (also known as fall in North American English) is one of the four temperate seasons, the transition from summer into winter. In the temperate zones, autumn is the season during which most crops are harvested, and deciduous trees lose their leaves. It is also the season where days rapidly get shorter and cooler, the nights rapidly get longer, and of gradually increasing precipitation in some parts of the world.

Definitions


Astronomically, some Western countries consider autumn to begin with the September equinox (around September 23) in the Northern hemisphere, and the March equinox (March 21) in the southern hemisphere, ending with the December solstice (around December 21) in the Northern hemisphere and the June solstice (June 21) in the Southern hemisphere. Such conventions are by no means universal, however. An exception to these definitions is found in the Irish Calendar which still follows the Celtic cycle, where autumn is counted as the whole months of August, September and October. In Chinese astronomy, the autumnal equinox marks the middle of autumn, which is deemed to have begun around the time of Liqiu (around August 7).
On the other hand,
meteorologists count the entire months of March, April and May in the Southern hemisphere, and September, October and November in the Northern hemisphere as autumn. Although the days begin to shorten after the summer solstice, it is usually in September (Northern Hemisphere) or March (Southern Hemisphere) when twilight becomes noticeably shorter and the change more abrupt in comparison with the more lingering ones of summer.
Autumn is often defined as the start of the school year, since they usually begin in early September or early March. Either definition, as with those of the seasons generally, is somewhat flawed because it assumes that the seasons are all of the same length, and begin and end at the same time throughout the temperate zone of each hemisphere


Autumn andtourism

Although color change in leaves occurs wherever deciduous trees are found, colored autumn foliage is most famously noted in two regions of the world: most of Canada and the United States; and Eastern Asia, including China, Korea, and Japan.
Eastern Canada and the
New England region of the United States are famous for the brilliance of their "fall foliage," and a seasonal tourist industry has grown up around the few weeks in autumn when the leaves are at their peak. Some television and web-based weather forecasts even report on the status of the fall foliage throughout the season as a service to tourists. Fall foliage tourists are often referred to as "leaf peepers".
